APPARATUS FOR APPLYINQ` TERMINAL YWIRES T0 ELECTRIC-LAMP GLOWERS.

SPECIFICATION forming part of Letters Patent No. 728,567, dated may 19, i903.

Applimm ind Apru 10,1902. lsans No. 102,309. (No modelo Pennsylvania, have invented a new and usef fnl Improvement in Apparatus for Applying Terminal Wires to Electric-Lamp-Glowers, (Case No. 1,047,) of which the 'following is a specification.

A My invention relates to the manufacture of electric-lamp glowers which are conductors only when heated to comparatively high 'temperatures.

, The object of my invention is to provide a means for attaching terminal-wires to glowers ina simple, inexpensive, and expeditious manner andso as to insure satisfactory electrical and mechanical union between said parts.

In the accompanying drawings, illustrating my invention, Figure 1 is a side elevation .of a glower-blank and the two terminal wires 'be- -fore attachment to the blank.- Fig. *2 is a as illustrated, comprises a rectangular frame 1, the base portion 2 of which is provided with an oblong rectangular recess or guideway 3, and iuthis recess is mounted the bottom portion 4 of a two-part block 5, this block being of less length than the recess or guideway 3, but of substantially the same width, it being fitted, however, so as to slide easily therein. The frame 1 comprses-aeclamping block or piece 6 at each end, which is suitably fastened to the base portion 2, the means here shown being dowel-pins 7, which project upward from the base and t into corresponding holes in the pieces 6. These pieces 6 are also provided with handles 8, by means of which they may be placed in and removed from their operative positions in the apparatns. The top part 9 of the block 5 is fastened to the bottom part 4 by dowel-pins 10, projecting upward from the lower part and li-tted into corresponding holes in the upper part. This part 9 is also provided with a handle'll, by meansot which it may be placed in and removed from its operative position. The two ends of the parts 4 and 9 are provided with registering semicylindrical-recesses 12 and 13 of the right dimensions to receive a glower-blank. The parts are also hollowed out to form an.enlarged semicylindrical re cess 14. The parts 2 and 6 are also preferably provided with smallv registering grooves to receive the terminal wires 15, the grooves p being of such dimensionsthat the wires may be clamped firmly in position, so that the.

amount of terminal-wire end Awhich it is' desired to insert into the glowersblankshallV project within the recess 3 at the upper side In applying the terminal wires 15 I place,

.the other-forV example, to theposition indicated in Fig. 3which will serve to force the end of the terminal .wire into the end of the blank. The piece 6 at that endmay then`be raised slightly or entirely removed to release the wire 15 and the block be then moved inV the guideway to the other end thereof, thus forcingthe end of the 'right-hand terminall wire in'to the corresponding'end of the glower- Ablank. The glowersblank and its terminal wires, which present the appearancey indil cated in Fig. 4, maythen be removed -from the apparatus and a suitable past-e 17 applied to the ends of the blank. The device may be then baked or otherwise subjected to'any treatment which may be n ecessary or desir- -of lead-wires to the terminal wires 15, it being the usual practice to employ platinum ICO for the terminal wires 15 and to fuse additional lengths of wire of less expensive material to the ends of these terminal wires.

Sincel the application of a highdegree of heat to a gloiver-blank serves to etect ashrinkage of the material, the terminal wires which are applied in accordance with my invention are securel y anchored in position by such shrinkage.

I desire it to be understood that my invention is not to be restricted to the specific apparatus shown and described, except in so far as limitations may be imposed' by the prior art and expressly set forth in the appended claims.Y

l; The colnbination with a frame provided at its respective ends with clamps for terminal wires, of amro-part block mounted to slide in said frame and adapted to holil an unbaked glower in alinement with the terminal wires which are held in and project from said clamps. Y

2. A device ufor attaching terminal Wires to glowers comprising a frame having terminalwire clamps at its ends and aclamping glowerholder mounted in said frame and movable longit ndinally therein to force the ends of the respective terminal wires into the corresponding ends of the glowers. i

e', An apparatus for attaching terminal wires to glowers comprising a frame having a guideway and terminal-wire clamps at the respective ends of said guideway and a glowerholder mounted in' said guideway and movable longitudinally to force the projecting ends of the terminal wires into the ends of the glowers.

4. The combination with a frame having a gruidewayand provided at its ends with clamps for terminal wires, of a glowerholder mounted to 'move along said-guideway against or into close proximity to said clamps.

In teslimony whereof I have hereunto subscribed my name this 4th day of April, 1902.

JOS. M. GULENTZ.
